Description/Abstract A study was conducted to provide the data to form the basis for a method to test the corrosiveness of various thermal insulating materials used in residential structures.^The insulating materials tested included celluloses containing several different fire-retarding additives, glass fibers some of which had been intentionally made more corrosive, mineral wool and urea-formaldehyde (UF) foam.^Experiments were conducted with steel, copper and aluminum coupons embedded in samples of the different insulating materials at 45/sup 0/C and 75% RH, both with and without a thermal gradient of 10/sup 0/C to cause condensation.^When there was no temperature gradient, the corrosion rates of the three metals tested were negligible indicating that in the absence of condensation or a water leak there is little likelihood of corrosion in the insulating materials tested.^Some field tests were conducted in attics in three locations.^Steel, copper and aluminium coupons were placed in the attics in a way to enable condensation to occur.^Several possible accelerated test procedures were investigated.^Because of the widely differing physical properties of thermal insulating materials used in residences and because some insulations were not wetted so as to provide a continuous electrical path which is a necessity for the electrochemical methods, it became apparent that leachants had to be used.^The justification for using leachants was that the test results showed that the corrosive electrolyte appears to be moisture containing soluble ingredients of the insulating materials.^Two test methods involving leachants correlated sufficiently well with the condensation and attic tests and met most of the other test criteria to qualify as possible corrosiveness-test procedures.
